Sunburst is Nani's horse. He is a Palomino American Paint gelding with a white mane and tail with yellow highlights and also has light blue tack. Sunburst has hazel eyes. He prefers to be ridden bareback, since he can not stand saddles and only wears them when absolutely necessary. At first he had bad terms with Pepper, although the two become friends.
He has a single braid in his mane, and his symbol is a yellow and blue sun. He has light blue saddle, bridle, and saddle bag, and blanket. He also has a silver triangle bridle ring, bit, saddle ring, and stirrups.
